ICT Loongson-2 V0.3 FPU V0.1, Linux 3.12.24-rt38 (Profile)

Latency plot of system in rack #2, slot #4
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l100000000 -m -n -p99 -i200 -h400 -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes
Characteristics of the 50 highest latencies:
